Description

EMBEDDED COMPLEX DEVICE WITH A HEAT TREATMENT FUNCTION FOR SKIN INFLAMMATION AND A REPELLING INSECT FUNCTION}

The present invention relates to electronic devices against insect bites, and more particularly to portable devices.

Various methods have been tried to combat mosquitoes.

As part of such an attempt, mosquito scents, mosquito aerosols, electronic mats, liquid fumigants, and electronic mosquito nets are known. However, long-term use of mosquito scents, mosquito aerosols, electronic mats and liquid fumigants are harmful to the human body, causing discomfort and headaches. Liquid fumigation, in particular, is known to be very harmful to children and pregnant women. In addition, in the case of the electronic mosquito net is to kill the mosquitoes by a high voltage, which is inconvenient. Some modifications of electronic mosquito nets use UV tubes, but not only are they noise, they are not safe for children.

As another prior art, mosquito repellent using ultrasonic or low frequency is known. The constant ultrasound generated by mosquito repeller aims to mimic male mosquitoes. Not all mosquitoes bleed human blood, but after mating, the female mosquito has been found to be vampire for spawning. By the way, the female mosquitoes of spawning stages do not need any more mating, instinctively avoiding male mosquitoes, and by applying this natural phenomenon is the method of blocking the access of blood-sucking mosquitoes by generating ultrasonic waves. In addition, the maximum natural enemy of the mosquito is known as a dragonfly, by applying this to generate a low frequency of a predetermined band to mimic the sound generated from the dragonfly wings, thereby preventing the access of vampire mosquitoes. Korean Utility Model No. 336202 is representative of such prior art documents.

However, all of these prior arts are merely means for preventing the mosquitoes from vampering blood, and are not measures against the case of mosquito bites. It is known that such measures work to some extent, and there are many products on the market, but that does not mean 100 percent mosquitoes. In addition, to treat various itching caused by mosquito bites by family, friends or others in close proximity, a separate treatment must be prepared and used.

A reaction that occurs when a mosquito bites itchy scratching the skin, first causing skin redness, then spreading around the skin, followed by dimples on the scratched area. This phenomenon is caused by the effect of histamine on blood vessels. In the immune response, histamine dilates blood vessels and increases the permeability of the blood vessel walls to allow more active immune system components to pass through the vessel walls and injure or move to infected tissues. Do it. At the same time, antihistamine, which selectively blocks histamine action, is expressed and enters the active site of histamine to block the reaction by histamine. At this time, itching occurs and itching and scratching by hand causes more side effects. As a treatment for this, a lot of steroids, which are antihistamines, have been used as chemotherapy, but the side effects are serious, and nowadays, such a therapy has been avoided.

A basic object of the present invention is to provide a portable device having a single housing, which can be prevented from being bitten by a mosquito using sound waves, and at the same time, a portable device can be treated immediately when the mosquito bites. That is, the present invention aims to provide a portable device capable of combating mosquitoes and treating them at the same time.

In addition, another object of the present invention is to provide a portable device capable of generating ultrasonic waves of a predetermined band or generating low frequencies of a predetermined band by user's selection by distinguishing sound waves generated in the apparatus into two modes.

On the other hand, other unspecified objects of the present invention will be further considered within the range that can be easily inferred from the following detailed description and effects.

Is installed outside the housing, including a selection switch for commanding a control signal to the acting portion,

The mosquitoes are eradicated using the sound waves generated by the sound wave generator, and the heat generated from the heating unit is applied to the skin to treat the mosquito bites.

In a preferred embodiment, the power supply unit may be a battery or a rechargeable battery including a charging circuit unit.

In addition, the sound wave generator is a first frequency band and dragonfly that is generated while converting the ultrasonic waves in the range of 2kHz ~ 50kHz corresponding to the blade frequency of the male mosquito randomly or sequentially into a frequency set to a large number within the range Sound waves are generated in any one of the second frequency bands generating a frequency in the range of 20 Hz to 200 Hz corresponding to the wing frequency of the dragonfly,

Preferably, the selection of the first frequency band and the second frequency band is determined by the selection switch.

In addition, in starting the treatment by operating the heating unit, it is preferable to set the treatment time and automatically terminate the operation of the heating unit when the set treatment time elapses.

In addition, preferably, an electrode handle is provided on the side of the housing by hand, the tip for contacting the skin has a polarity opposite to the electrode of the electrode handle, by stepping up the voltage supplied from the power supply to the The method may further include applying electrical stimulation to the affected part of the mosquito bite through the skin contact tip.

According to the present invention as described above, as a portable device consisting of a housing, it is possible to fight the mosquitoes using sound waves, and at the same time has the advantage that can be treated immediately when the mosquito bites. This works for mosquitoes as well as other bugs.

In addition, the treatment effect can be doubled by applying a certain electrical stimulation in treating the mosquitoes.

In addition, since the sound waves generated in the present invention can be divided into two modes to generate ultrasonic waves of a predetermined band or low frequencies of a predetermined band by user selection, the mosquito repelling effect can be doubled.

Although effects not specifically mentioned in the specification of the present invention, it is added that the potential effects expected by the technical features of the present invention are treated as described in the specification of the present invention.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the following description of the present invention, when it is determined that the subject matter of the present invention may be unnecessarily obscured as matters obvious to those skilled in the art, such as related well-known functions, the detailed description thereof will be omitted.

Fig. 1 shows a housing structure of an embodiment according to the present invention, Fig. 2 shows an example of its use, Fig. 3 shows an example of the interior of the housing, and Fig. 4 shows an example of the entire operating process.

As shown in FIG. 1, the housing 1 of the device of the present invention is of a size and shape that a user can hold with one hand. On the outer surface of the housing 1 may be a power switch 40 and a selection switch 50 for selecting a function. The selector switch 50 may select whether to fight the mosquito or the treatment mode for treating the mosquito bite affected area. In another embodiment, the long press of the power switch 40 causes the device to be turned on, and then the short press of the switch 40 enters the treatment mode, and the selector switch 50 has a frequency band, for example A wing frequency of a male mosquito or a wing frequency of a dragonfly may be selected. In addition, a tip 10 for skin contact is installed at the end of the housing 1. The skin contact tip 10 is selected from a member having good heat transfer. Preferably it is a metal member and a ceramic member can be used. As shown in FIG. 2, the skin contact tip 10 contacts the skin affected by mosquito bites, and heat at a predetermined temperature is applied within a predetermined time range. In some cases, electrical stimulation may be applied simultaneously or sequentially.

Based on the internal configuration and control flow of FIG. 3, in connection with the functionality of the present invention, an electrical stimulation mode may be added to the two functional modes, in other embodiments the treatment mode. In the present invention, the working part is installed in the housing 1, and may include a heating part 70 and a sound wave generating part 80. In another embodiment, the booster 90 may be further included.

<Sound Wave Control>

Acoustic wave control relates to mosquito control mode. The sound wave generator 80 applies a voltage to the piezoelectric buzzer to generate sound waves in a predetermined frequency band. Since generating the frequency using the piezoelectric buzzer itself is a well-known means, a detailed principle will be omitted. However, in the sound wave generator 80 of the present invention, two frequency bands may be set to effectively combat mosquitoes. The first frequency band refers to ultrasonic waves in the range of 2 kHz to 50 kHz corresponding to the blade frequency of the male mosquito. In addition, the second frequency band generates sound waves having a frequency in the range of 20 Hz to 200 Hz corresponding to the wing frequency of the dragonfly. The selection of the first frequency band and the second frequency band may be determined by pressing the selection switch 50.

The microcomputer 100 receives a command from the selection switch 50, and controls the operation of the sound wave generator 80 to generate sound waves within a preset frequency band. In addition, the microcomputer 100 randomly generates sound waves in the first frequency band of the sound wave generator, or generates an operation while sequentially converting frequencies according to the order of a plurality of input frequencies set in the first frequency band. To control.

<Heating control>

The heating unit 70 applies a current to a heating element (heater) built in a position adjacent to the skin contact tip 10 through a heating circuit to heat the heating element to a set temperature, and the heated heat to the skin contact tip 10. To pass. Preferably the temperature is set in the range of 45 ~ 90 ℃.

In addition, in delivering heat heated through the skin contact tip 10 to the skin affected by the mosquito bite, the treatment time can be set. For example, in the range of 45 to 55 ° C., a time range of 30 to 150 seconds, preferably at 50 ° C. for 120 seconds, and at a temperature of 56 to 65 ° C., for a time range of 30 to 60 seconds, preferably at 60 ° C. for 60 seconds, 66 In the temperature range of ˜90 ° C., a time range of 1 to 30 seconds may be set, preferably 2 seconds at 80 ° C. When the heating system is operated by the start of heating of the heating unit 70 to reach the set temperature, the treatment is started and the power supplied to the heating unit 70 is cut off when the set time is reached at the set temperature.

The microcomputer 100 receives a command from the selection switch 50 and controls the operation of the heating unit 80 to operate according to a set temperature and a set treatment time.

<Electric Stimulation Control>

When looking at the housing 1 in front with respect to the selection switch 50, the handle electrode 20 may be installed on both sides of the outer surface as a part held by the user by hand. The skin contact tip 10 is made of a conductor and has a polarity opposite to that of the handle electrode 20. For example, if the handle electrode 20 is a (-) electrode, the skin contact tip 10 becomes a (+) electrode, and when the tip 10 is brought into contact with the user's skin, the entire circuit between the human body and the device becomes conductive and the potential Is set and has a bactericidal action to attract macrophages. As such, by forming an electric potential between the human body and the device and applying electrical stimulation, the treatment function for the mosquito bite affected area may be enhanced.

The booster 90 boosts the voltage supplied from the power supply unit 60 to a voltage within 10 to 500 V and applies electrical stimulation to the mosquito bite affected part through the skin contact tip. In salty skin, electrical stimulation produces a small amount of sodium hypochlorite. Electrical hypochlorite has a strong bactericidal power.

NaCl + H2O + 2e- → NaOCl + H₂ ↑

The human body always releases salt-containing sweat through the skin through the pores, and when the electrical stimulation is applied thereto, a therapeutic effect occurs.

On the other hand, the circuit configurations can be mounted as circuit elements on one PCB. In addition, the power supply unit 60 may use a battery, for example, AAA batteries, and in the preferred embodiment may be equipped with a rechargeable battery. When the rechargeable battery is mounted, the power supply unit may include a charging circuit unit.
